A. This heater has a pilot that must be lit manually. When
lighting the pilot follow these instructions exactly.
B. BEFORE LIGHTING smell all around the heater area
for gas. Be sure to smell next to the floor because some
gas is heavier than air and will settle on the floor.
WHAT TO DO IF YOU SMELL GAS
-
Do not try to light any heater.
- Do not touch any electric switch; do not use any phone
in your building.
- Immediately call your gas supplier from a neighbor's
phone. Follow the gas supplier's instructions.
- If you cannot reach your gas supplier, call the Fire
Department.
C. Use only your hand to push in or turn the gas control
knob. Never use tools. If the knob will not push in or
turn by hand, don't try to repair it. Call a qualified service
technician. Forced or attempted repair may result in a
fire or explosion.
D. Do not use this heater if any part has been under water.
Immediately call a qualified service technician to inspect
the heater and to replace any part of the control system
and any gas control which has been under water.
Figure 3.
WARNING
If you do not follow these instructions exactly, a fire or explosion may result causing personal injury,
loss of life and property damage.
Since propane gas is heavier than air, escaping propane will accumulate and remain at ground level. Do
not attempt to light the heater. If you suspect a propane leak, lighting the heater can result in a fire or
explosion which can cause personal injury, death, and property damage.
